ultrasonic blind helper works on the principle of detecting object in front of ultrasonic device (similar procedure of finding objects by bats) . for this equipment we have to design an ultrasonic transmitter and receiver and along with micro controller circuit to analyse the object and give alert to blind using buzzer , this transmitter and receiver devised on blind's guide stick and using a radio signal information of ahead object transmit to head phone (alternatively we can use Bluetooth technology here). transmitter always emit ultrasonic waves if any object come in front of the transmitter which will reflect back and these ultrasonic signal can receive by ultrasonic receiver
